Just learned that i am pregnant

Hello. Me and my husband tried to conceive for our 2nd child for almost a year. Every month, i am heartbroken when my period came. Thanks God, I just learned yesterday that I am pregnant. But it's really true that when you least expect to get pregnant, that's the time you'll be pregnant. To cut it short, for the previous months I have always assumed that anytime I will be pregnant, and so I have been very careful in using skincare products and careful in drinking/taking supplements. This time (before i knew i was pregnant), I was not quite mindful, I used a skincare containing salicylic acid, aha/bha (due to pimple breakouts), i was drinking a slimming coffee and senna tablets as well. Ofcourse I stopped it now that I knew Iam at 5weeks AOG but I am quite worried. Anyone who experienced the same situation as mine? Thank you!
